mne.read_morph_map

mne.read_morph_map(subject_from, subject_to, subjects_dir=None, xhemi=False, verbose=None)[source]

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more).

Returns:
left_map, right_map : ~scipy.sparse.csr_matrix

The morph maps for the 2 hemispheres.
